  • PPA's are personal package archives which only have the security checks you perform on them yourself, did you do any checks? A quick look at https://launchpad.net/~tualatrix/+archive/ubuntu/personal (from your question) shows the repository was last used in 2013 thus provides no support for any modern Ubuntu, are you attempting to explore security problems? Remove it asap. – guiverc May 03 '23 at 06:26
  • Apparently you can still login with your password, but if you can't login read this: How do I reset a lost administrative password? – karel May 03 '23 at 08:12
